PRD-3

The Gato Audio PRD-3 preamplifier features low noise analogue circuitry, true 24bit/192Khz conversion, upsampling of the lesser quality and a very clean internal clock generator for ultra low jitter in the digital domain.
 
Smooth analogue music
The analogue input stage is where everything begins. It not only connects external inputs and the built-in D/A converter with the output stage, it adapts impedances, adjusts levels and switches signals. A super-gentle embrace of the delicate analogue signals is important for the total performance of the preamplifier. At Gato Audio we have utilized our many years of experience in "voicing" analogue amplifiers to make this particular stage perform at its very best. We tuned the input stage to perform with a natural and lifelike sound, affecting the original signal as little as possible.
 
More than just a Preamp
The built-in D/A converter offers real high end performance, enabled by the use of a dedicated power supply, a balanced-drive Burr-Brown PCM1794 D/A converter, an optimized high bandwidth I/V converter, and an analogue stage with low-Q, low pass filters. All digital inputs are upsampled to 24bit/192kHz. This D/A converter will upgrade any digital source - such as wired or wireless streaming from your computer or CD drive - to a high end level of detail and musical performance.
 
Versatility and Connectivity
We had our eye on versatility and connectivity when designing this preamplifier. The PRD-3 offers not only a wide range of digital and analogue inputs, but also line outputs, a trigger signal for external power amplifiers, and a configurable home theater input. The HT input can turn the preamplifier into a fixed level preamplifier for use in a surround setup, without compromising the sonic performance.
